383' shuts off' issues, I tried praying, no luck

Did not know definitively where else to post this , so move if needed.

OK so I’m old- I grew up on points & condenser, and one coil for all 8 cylinders. And something called a carburetor. (hey, they still work on lawn mowers!) – Anyway I got this old school mopar Sweptline truck I’m working on with 383, and it’s giving me ulcers. I’ve always been damn good at this sort of resurrection stuff and fairly patient. The truck was sitting for some 30 years. The whole fuel system is cleaned & tank sealed now. The New fuel pump with in-line filter added, NEW points/condenser, cap/rotor, wires coil & plugs. The Carter BBD 2 bbl carb is rebuilt & spotless inside. So the truck keeps just shutting off. It may or may not start right up. It shuts off with a little bit of an accelerated idle then the sucking noise like it’s running out of gas. I actually had the truck running with the whole top of the carb OFF and it’s not starving for fuel when it shuts off (note* Coolest thing I have ever done with a carb}. During the warmer weather it might idle for 15 minutes, but it seems worse since it got colder out or maybe what ever is breaking down is getting worse.? I tried bypassing the resistor, running a hot wire to the positive side of the coil, fiddling with all of Mopars lousy firewall connection and NOTHING seems to make a difference.
